Configure the Main Machine

Next, on the main machine:

• Under System → System Setup → System Wide Settings, add both the main and backup machines' IP addresses to Cluster Members (one per line). While not strictly necessary immediately, this keeps the setting consistent with the backup machine, in case the two switch roles.

• On the same page, under System Replication Settings / Targets, add a target, and enter the backup machine's IP address. This will begin to send settings changes and newly walked pages to the backup machine.

• Hit Update to apply the above changes.
